Abstract
INTRODUCTION
Frontal plane knee control is essential to athletic knee injury prevention.
AIM
To evaluate knee valgus frontal plane projection angle (FPPA), knee safety, and sports movement capability confidence during single leg triple hop for distance (SLTHD) under knee sleeve, distal thigh compression garment (DTCG), and no device (control) conditions.
METHODS
A single-session, experimental study was performed using a within-subject design, and randomized device order. Two-dimensional FPPA measurements were collected during the final SLTHD landing of 18 healthy female college athletes for each condition. Sports movement capability and knee safety confidence were measured using 10-cm visual analog scale questions. One-way ANOVA assessed group differences, and Pearson correlations delineated FPPA, knee safety and sports movement capability confidence relationships (p < 0.05).
RESULTS
The DTCG group had less valgus FPPA than the control group. The knee sleeve group had greater knee safety confidence than the control group. The DTCG (r = 0.48) had a moderate positive relationship between mean SLTHD and knee safety confidence. The DTCG group also had a moderate relationship between maximum SLTHD and knee safety confidence (r = 0.52). The DTCG and knee sleeve groups displayed moderate direct, and moderate inverse relationships between FPPA and sports movement capability confidence (r = 0.48 and r = -0.44, respectively).
CONCLUSION
Reduced FPPA and relationships between maximum SLTHD magnitude and knee safety confidence, and between FPPA magnitude and sports movement capability confidence suggests that the DTCG may enhance pelvic deltoid kinesthetic acuity and dynamic knee stability through iliotibial tract compression.
CLINICAL RELEVANCE
The DTCG was superior to the standard knee sleeve or control conditions for displaying characteristics that might better prevent knee injury, while still enabling effective sports movement capability.
